If the temperature difference between morning and evening is relatively large, water droplets and moisture are more likely to form. Moisture invades the cabinets of power equipment, forming condensation inside, which may lead to internal corrosion, or even short circuits in the lines, leading to fires and posing a serious threat to normal power production activities. Therefore, power operation and maintenance personnel should frequently carry out moisture-proof and leak sealing operations on the equipment. However, there is a small issue:Sealing at the bottom of the cabinetHow can we block moisture faster and more efficiently?

　　How can the sealing at the bottom of the cabinet block moisture faster and more efficiently? Why does fireproof mud have such a problem? The reason is that the fire resistant mud on the market is uneven, divided into national standard fire resistant mud and non-standard fire resistant mud. The national standard fireproof mud is made of flame retardant and pure paraffin wax, which can be fireproof and waterproof. Non standard fireproof mud is made of flame retardant and chemical oil, which is flame retardant but not waterproof, and is prone to cracking and oil flow over time.

　　So, is there a better plugging material? After scientific research and development, polymer materials can be used as a good plugging tool and will not crack, oil flow, or collapse like fireproof mud. For example, foamed polyurethane materials can be quickly foamed and molded on the working surface, achieving a flame retardant effect.

　　However, this approach still has some shortcomings. One is that if the working face is narrow and there is not enough space, it is difficult for manual workers to apply sealing materials on the working face. Secondly, if it is manually applied, although it can be automatically leveled, the working surface may not be as neat and beautiful; The second issue is that manual application is often difficult to grasp, as you can use as much as you need without wasting time and effort. It is time-consuming and laborious to control.

　　How can the sealing at the bottom of the cabinet block moisture faster and more efficiently? At this point, we can learn about a new method, which is spray plugging. This is a method of mechanically spraying the working surface with a spray or spraying equipment. Firstly, the machine is small in size and easy to carry, allowing for construction on narrow working surfaces without being affected; Secondly, by adjusting the discharge speed and quantity of the machine, uniform spraying can be achieved and the working surface is beautiful and tidy. Once again, due to uniform spraying, its quantity is controllable, faster than manual spraying, saving time and effort, and supporting uninterrupted power supply operation.
